O skewed right O symmetric The mean weight of the candies is grams (Type an integer or deomal rounded to the nearest thousandth as needed The median weight of the candes is grams (Type an integer or decimal rounded to the nearest thousandth as needed. Which measure of central tendency best describes the weight of the candy? Cick to select your answer(s). O Ask me anythingExplanation / Answer
A) C option as from 0.79 to 0.82 we have 0.81. So, C option suits this.
B) When data are skewed left, the mean is smaller than the median. If the data are symmetric, they have about the same shape on either side of the middle. In other words, if you fold the histogram in half, it looks about the same on both sides.Data is skewed left in this histogram.
C) Mean = (0.92 + 0.90 + 0.89 + 0.92 + 0.92 + 0.87 + 0.93 + 0.87 + 0.81 + 0.90)/10 = 8.93/10 = 0.893
